TO ALL WHOM IT MAY CONOERN:

Be it known that I, ADOLPH F; KUHLMAN', of Dubuque, in the county ofDubuque, and State of Iowa, have invented a new and useful Improvementin Washing Machine; and I do hereby declare that thc following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the sume, reference being had to theaccompanying drawings, forming part of this-specification, in which-Figure 1 is a vertical cross-section of my improved machine, takenthroughthe line :v fig. 2.

Figure 2 isa top'view of the same. i

Similar letters of reference indicate like parts. l

My invention has for its object to so improve the construction of mywashing machine patented August 7, 1866, and numbered 56,955, as to makeitsmpler in construction and more elfective in operation; and itconsists in the combination of the smooth rubbers and inclined rubberand feed-boards with thevibrating arms or plates and shaft; in thecombination of the pivoted staffers with the feed-boards, vibratingarms,and tub; and in the combination of a'pivotcdguard-board, orequivalent, with the stuifers and with the vibrating frame; the wholebeing constructed and arranged as hereinafter more fully described. i

A is the box or tub, the bottom of which may be made of sheet iron orother suitable material; is made semi-cylindrical in its general form,and is lined with corrugated sheet zinc or other suitable material for arubber-board. The forward side of the bottom departs a little from thecircle and passes upiin a direction a little nearer a straight line thanthe arc of a circle would be. B is a cylinder or shaft, the ends ofwhich are pivoted to the ends of the tub A, and which has arms or platesC attached to it near its ends. D are smooth rubbers, attached to thelowcrcurved edges of the plates C in suc-h a way as to leave a spacebetween their inner edges, as shown in fig. 1. E are feed andrubber-boards, the ends of which are attached to the vibrating plates Cso that the said boards may stand in an inclined position, with theirlower edges projecting between the-inner edges of the rubbers D, leavinga space'between their own lower edges-for the passage of the clothes.The lower edges of the inclined feed-boards E are rounded off, as shownin iig. 1, so as to act as rubbers upon the clothes; and the said boardsare also perforated, to allow the water to have. a free passage throughthem as the machine is being operated. F are the stuffers, the ends ofwhich are pivoted 4to the ends or frame of the tub, and which hang down,with their lower edges upon or near the inclined feed-boards E. Thestuifer-boards F are perforated in their lower parts for the freepassage of the water. As the rubber-frame'is vibrated the lower edges ofthe stuffers F are forced into the space between the lower edges of theinclined feed-boards E, so as to force the clothes through to beacted'npon by the rubbers. G is a bar or board, the ends of which, nearits upper edge, are pivoted to the plates or arms C between the stuersF, to prevent the clothes from passing too fast into the feed-box. Theform of the bar G is immaterial; a cylinder may be used if desired. H isthe feed-apron upon which the clothes to be washed are placed, and bywhich they are guided into the feed-box. I is the handle or lever bywhich the machine is operated, and which is connected with the shaft B.In using the machine the clothes will always pass out at the front ofthe rubbers, and at each vibration they will be forced up against thelongitudinal bar J and the dirty water squeezed out, and each lot ofclothes may be left inthe front part of the tub to be thus acted uponwhile the nextlot is passing through the feed-box and rubbers.

What I claim as new, and desire to secure by Letters Patent, is=

1. The combination of the smooth rubbers D and inclined rubbing andfeed-boards E with the vibrating arms or plates C and shaft B,substantially as herein shown and described, and for the purpose setforth.

2. The pivoted stnifers F, in combination with the inclined feed-boardsE, vibrating arms or plates C and tub A, substantially as herein shownand described, and for the purpose set forth 3. The combination of thepivoted guard-board Gr, or equivalent, with the stuiers E and vibratingarms or plates C, substantially as herein shown and described, and forthe purpose set forth.
